RMG管桁架大梁结构的改进

Modification on RMG's Girder Structure with Tube Truss

为了使RMG的大梁结构减重,研究并改进一种三角形管桁架的大梁结构。这种新型包容式节点连接形式能提高桁架大梁结构的使用寿命。对新型大梁结构实物进行试制,并验证改进后的包容式节点管桁架大梁结构在减重和制造方面的优越性。

A triangular-shaped girder structure with tube modified to reduce the mass of RMG＇s girder structure. truss is researched and The new type connection with inclusive joint is designed to increase the service life of the girder structure. The prototype experiment of the new girder structure is carried out. The superiority of the modified girder structure with tube truss and inclusive joint is verified in the aspect of weight loss and manufacture.
